Having flown in a Dolphin, I can attest that buying the best vehicle for the mission doesn’t apply to Congress, which insisted that the power plant around which the Dolphin was designed, be replaced by a much heavier GE turbine, resulting in a heavy chopper that had to eliminate safety equipment in order to be able to fly. The ergonomic crash seats were replaced by simple metal frames with cloth slings, that were so uncomfortable, they affected crew performance and caused repetitive stress injury.
